Earth's Lucky Party
Why is Earth the only planet we know of that has life?
Look up at the night sky, and you'll see thousands of worlds — yet so far, every single one of them is empty. No birds, no bugs, no bacteria. Just Earth, glowing blue and busy and impossibly alive. So what's our planet's secret? Plot twist: it's not one secret. It's a whole stack of lucky ingredients, all in the same place at the same time.
Ingredient one: standing in just the right spot. Earth orbits the Sun in a cozy zone scientists call "the Goldilocks zone" — not too hot, not too cold, but just right. Get any closer and our oceans would boil away. Drift too far and they'd freeze solid. We landed in the sweet spot.
